Renewable-energy-powered electrochemical CO reduction (ECR) is a promising way of transforming CO to value-added products and achieving sustainable carbon recycling. By virtue of the extremely high exposure rate of active sites and excellent catalytic performance, atomic site catalysts (ASCs), including single-atomic site catalysts and diatomic site catalysts, have attracted considerable attention. In this feature article, we focus on the rational design strategies of ASCs developed in recent years for the ECR reaction. The influence of these strategies on the activity and selectivity of ASCs for ECR is further discussed in terms of electronic regulation, synergistic activation, microenvironmental regulation and tandem catalytic system construction. Finally, the challenges and future directions are indicated. We hope that this feature article will be helpful in the development of novel ASCs for ECR.
可再生能源驱动的电化学CO还原（ECR）是将CO转化为增值产品并实现可持续碳循环的一种有前景的方法。由于活性位点的极高暴露率和优异的催化性能，包括单原子位点催化剂和双原子位点催化剂在内的原子位点催化剂（ASCs）受到了广泛关注。在这篇专题文章中，我们聚焦于近年来开发的用于ECR反应的ASCs的合理设计策略。从电子调控、协同活化、微环境调控和串联催化体系构建等方面进一步讨论了这些策略对ASCs用于ECR的活性和选择性的影响。最后，指出了挑战和未来方向。我们希望这篇专题文章将有助于开发用于ECR的新型ASCs。
